GUIDE FOR LINOTYPEMACHINES.

Specication of Letters Patent. Patented NOV. 16, 192() Application ledFebruary 4, 1918. Serial No. 215,290.

-linotype machines for controlling the movement of linotype slugs.

The object of my invention is to provide a device for guiding the slugsor type-bars as they fall down the chute upon the stick or assemblyplatform, which shall be capable of being quickly and readily adjustedto guide long or short slugs; which shall be simple in construction;whichshall always be in position for use; and which shall be readilyeXtensible and retractable as to length.

My invention consists in an inclined stick or assembly platform adaptedto receive slugs of different lengths at its upper edge and down whichthe slugs are adapted to slide, in combination with a wall or guidewhich is adjustable as tov length so that either short or long slugs maybe properly guided as they descend the stick, to the end that whenv longslugs are produced the wall or guide may be retracted so as to notinterfere with the proper assembling of the slu s upon the platform. Y fy invention also consists inthe several features of construction and inthe arrangements and combinations of parts whereby I am enabled toattain the above mentioned and other objects and all as hereinafterdescribed and particularly pointed out in the ap endedclaims.

y invention will be more readily understood by reference to theaccompanying drawings forming a part of this specification, and inwhich:-

Figure 1 is a fragmentary side elevation, partly in section, of thefront part of the slug making mechanism of a linotype machine;

' Fig. 2 is a fragmentary front elevation of the portion of a linotypemachine shown in Fig. l;

Fig. 3 is an enlarged fragmentary vertical section on the line 3 3 o fFig. 2; and

Fig. 4 is a substantially horizontal section on the line 4--4 of Fig. 3.

This present invention is particularly related to and useful inconjunction with my inventlon of a type-bar sawing device as disclosedin my co-pending application Number 825,049, filed March 16 1914, forpatent on linotype machines. Ihe device of theformer application wasespecially adapted for producing linotype slugs or typefbars ofdifferent or varying lengths from a fraction of `an inch to five inchesor more, and in the use of said device upon llnotype machines ofStandard make, I have found a difficulty in properly assembling thedifferent lengths-of slugs upon the stick or assembly platform of themachine. My present invention has for its object the overcomingv of thisdiiculty.

In the said drawings 1 illustrates generally the forward part of theslug prov ducing mechanism of a linotype machine as provided with myslug sawing mechanism illustrated and described in'my said copendingapplication. l

-Linotype machines are usually provided with a mold wheel 2-providedwith mold slots 3 in which slugs 4 of substantially five inches inlength are cast. The machine also has a reciprocating slug ejector 5which is adapted to'force the Slug 4 out of the mold 3 when the same isin a vertical position, as shown in the drawings. As the slug is pushedout of the mol'd 4 by the ejector 5, it passes through a trimmingmechanism 6 by which'it is sized as to thickness, and in front of thistrimming mechanism I have arranged a slug cutting saw 7 in a casing 8.

The saw is carried by a shaft 9 and is movable up and down in front ofthe mold slot by the mechanism fully described in my said co-pendingapplication. The saw 8 is thus arranged for the purpose of cutting theslugs as they are ejected from the machine into an upper and a lowerpart. The upper part is waste and passes out of the machine down a wastechute, not shown, and the lower part carries printing characters and isthe article which it is desired to produce upon the machine. This loweror printing part 10 of the slug, as soon as it is severed from the upperpart, drops vertically down the narrow vertical chute 11 upon a curvedguide plate 12 by which it is turned with its forward or printing faceuppermost, and it then slides Vdown upon the downwardly inclined stickor assembly platform 13. As

shown'in the several figures,

upperl ed and, as il the stick is wide enough from itsl lowerV edge 14to its e 15`tov receive the lon est slugs,

of whatever lengths, ,slide down upon this platform until their/lowerends rest against the rib or ridge 14 atthe lower edge of the stick.'To' close 'one side of the chute 11 and immediatel thus form the narrowvertical chute down which the slugs drop, plate 17 which I extend at itslower end down over the upper part of the st ick 13. At the lower partofthe stick and 1n sub'- .stantial alinement with the plate 17 is adescribed as to its operation, except to say forms Vone wall ofthe slotdown w that as a slug slides down` it draws back into alinement with theplate 17 and out of the path of 'the descending slug, and then1mmediately moves forward and pushes the slug along the stick out of thepath of the next descending slu As best shown ingig. 2, the forward facelate 17, ich the slu l fall,'and my invention relates articular y to anextensible and retractab e'gulde which is adapted to form the oppositewall of the said chute or slot.

For this purpose I provide a jointed guide 20 formed of a series ofshort thin strips or bars 21 pivotally joined end to end and capable ofbeing folded back upon themselves, as shown Iin full line in Fig. 2, orextended in end to end relation, as shown in dotted lines in saidfigure. I pivotally mount this jointguide at one end to the linotypemachine at one side of the chute 11 near the lower end thereof or wherethe slugs strike the curved plate or guide 12. The guide 20 is set onedge and is capable of being extended or lengthened in position oppositeto the lower end of said plate 17 and the inner face 19 of the pusher 18so as to form the opposite wall of the chute down which the slugs moveon the stick 14. I make the guide 2() yieldable laterally so that evenshould a slug be caught between the end of the pusher and the guide nodama e can result.

It will now be c ear that I am enabled to guidethe extremely short slugsas well as the longer ones, chine from producing short slugs to produc-19 of the pusher, together with the ustrated'in Fig.- 2, allo the slugs,

I provide the thin stick. This and when Ichange the mainglonger ones, Ican readily shorten the guide 20 to vpermit longer slugs to be properl7assembled by the pusher 18-' will also be plain that I can quickly andreadily lengthen or shorten the guide' 20' to properly guide any lengthof slug which can be produced upon the machine,

and that when producing full length slugs the guide can readily befolded back out of 'ducing type bars of various lengthsv and having aninclined stick or slug assembly platform, the combination therewith of arlaterally yieldable slug guide extending over saidplatform, said guidebeing retractable and extensible for accurately guiding type bars'ofvarious lengths as they slide down said inclined assembly platform. 2.In a'linotype machine capable of producmg type bars of various lengthsand having an inclined stick or slug assembly platform down which theslugs are adapted to slide to be assembled in column form, a slugassembly member adapted to push the slugs laterall into column form, anda foldable gui e arranged over said stick adapted to be pulled out orpushed back to adjust its length to correspond with the length of theslugs being produced, and said guide being yieldable inthe direction ofthe transverse movement of thev slugs as they are assembled into columnform to prevent inadvertent stoppage of the slug assembler.

3. In a machine of the kind described, having an inclined assemblyplatform down which the type bars slide'to be assembled in column form,a guide projecting over the platform composed of a plurality ofyieldable members pivotally joined at their ends and adapted to beextended over the platform in end to end relation to guide short lengthtype bars down the platform and adapted to be folded back in parallelrelation to properly guide longer type bars down the assembly platformand to permit the longer type bars to be moved transversely by theassembler member.

In testimony whereof, I have hereunto set my hand this 2 day ofFebruary, A. D. 1918.
